Analysis of convective clouds characteristic in Ningxia;

,the characteristics of parameters and evolutive regularities of convective cloud in the mid-mountain region of southern Urumqi were analyzed in this study,including the echo top,and its intensity,occurrent periods,nat.

It is very meaningful to separate the precipitation cloud system into convective cloud and stratiform cloud.

The convection cloud is the main precipitation system in south China,having abundant water resource.

For researching the rule of convection cloud in Jianghuai area, we used Dual-doppler Radar in the experiment of weather modification about convection cloud.

Hail s strength are associated with convective cloud s evolution and strength.

The first strong precipitation is caused by strengthening local convective clouds generated in the subtropical high,vapor transportation and dynamic conditions offered by strengthened easterly flow in bottom of the troposphere air promote the development of convection;New clouds in the humid air environment will be rapidly strengthened and developed.

Based on analysing 9 cases of mesoscale convective cloud cluster over clod front cloud system during 1994~2002, it was found that the origin in which the mesoscale convective cloud was outgrowth located in middle and southern parts of Guizhou province .

The mainly features of mesoscale convective cloud clusters during four heavy rainfall stages in Changjiang River Basin have been studied by using GMS TBB data of every hour on every day from June to August in 1998.

Convective activities in the atmospheric boundary layer, for example the cloud streets, may generate gravity waves in the overlying stable layer, cause vertical momentum transport and affect the momentum budget in upper troposphere and stratosphere.
